Definitions
- the invention relates to a method for laser welding one or more workpieces of press-hardenable steel, in particular manganese-boron steel, in
- Butt joint in which the workpiece or workpieces have a thickness of at least 1.8 mm and / or at the butt joint a thickness jump of at least 0.4 mm is formed, and in which the laser welding while supplying additional wire into the molten bath generated by a laser beam he follows.
- Tailored blanks made of sheet steel are used in the automotive industry to meet high demands on crash safety with the lowest possible body weight.
- tailored blanks are used in the automotive industry to meet high demands on crash safety with the lowest possible body weight.
- individual blanks or strips of different material quality and / or sheet thickness are joined together in the butt joint by laser welding. In this way, different locations of the finished body component can be adapted to different loads. So thicker or higher-strength steel sheet can be used in places with high load and thinner sheets or sheets of relatively soft thermoforming grades at the other locations.
- Sheet metal blanks eliminate the need for additional reinforcing parts on the bodywork. This saves material and allows to reduce the overall weight of the body.
- boron-alloyed steels in particular manganese-boron steels, have been developed which achieve high strengths during hot forming with rapid cooling, for example tensile strengths in the range from 1500 to 2000 MPa.
- manganese-boron steels typically have a ferritic-pearlitic structure and have strengths of about 600 MPa.
- press hardening ie by heating to Austenitmaschinestemperatur and subsequent rapid cooling in the molding press, however, a martensitic microstructure can be adjusted so that the steels treated in this way can reach tensile strengths in the range from 1500 to 2000 MPa.
- the body components produced from such custom-made steel plates for example B-pillars, have a perfect hardness profile up to a certain sheet thickness or a certain thickness change. However, it was found that at a sheet thickness greater than or equal to about 1.8 mm, in particular
- the problem arises that the laser weld does not harden sufficiently during hot forming (press hardening). In the area of the weld then results only partially a martensitic microstructure, so that it can come under load of the finished component to a failure in the weld. This problem is probably related to the fact that in particular with a thickness jump usually sufficient contact with the cooled forming tool or cooling tool can not be guaranteed and thereby the weld can not be completely converted into martensite.
- US 2008/0011720 A1 describes a hybrid laser-arc welding method in which blanks of manganese-boron steel having an aluminum-containing surface layer are butt-joined together, wherein the laser beam is combined with at least one electric arc, to melt the metal at the butt joint and the boards together
- the electric arc is emitted by means of a tungsten welding electrode or forms when using a MIG welding torch at the top of an additional wire.
- the filler wire may contain elements (eg, Mn, Ni, and Cu) which induce the transformation of the steel into an austenitic structure and promote maintenance of austenitic transformation in the molten bath.
- the present invention has for its object to provide a laser welding process, with the workpieces of press-hardenable steel, in particular manganese-boron steel, which have a thickness of at least 1.8 mm and / or where at the butt joint a thickness jump of at least 0.4 mm arises, too
- tailor-made workpieces in particular tailor-made boards, can be joined in the butt joint, the weld seam of which can be reliably hardened into a martensitic structure during hot forming (press hardening).
- the process by a high productivity and a relatively low
- the inventive method is used for laser welding of one or more workpieces made of press-hardenable steel, in particular manganese-boron steel, in
- Butt joint in which the workpiece or the workpieces have a thickness of at least 1.8 mm, in particular at least 2.0 mm, and / or a thickness jump of at least 0.4 mm occurs at the butt joint.
- the laser welding takes place while feeding filler wire into the molten pool generated with a laser beam.
- the filler wire contains at least one alloying element of the group comprising manganese, chromium, molybdenum, silicon and / or nickel, which promotes the formation of austenite in the molten bath produced by the laser beam, this at least one alloying element with a mass fraction which is greater by at least 0.1% by weight in the additional wire than in the press-hardenable steel of the workpiece or of the workpieces.
- the hot forming press hardening
- the workpieces or custom-made blanks produced according to the invention offer a larger process window in which a sufficient hardening of the component, in particular also in its weld seam, is achieved.
- the inventive method can be used not only when joining several steel blanks of different material quality and / or sheet thickness in the butt joint, but also, for example, the laser welding of a single plate or strip-shaped steel sheet, in the latter case, the edges to be welded together of the workpiece by forming, for example by folding or roll forming, are moved towards each other, so that they are finally arranged facing each other in the butt joint.
- the workpiece or the workpieces are selected such that their steel has the following composition: 0.10 to 0.50 wt .-% C, max. 0.40 wt.% Si, 0.50 to 2.00 wt.% Mn, max. 0.025% by weight P, max. 0.010% by weight of S,
- Press hardening have a tensile strength in the range of 1500 to 2000 MPa.
- a further preferred embodiment of the method according to the invention is characterized in that the additional wire used therein follows
- Composition comprising:
- the filler wire used therein has at least 0.1 wt .-% lower carbon mass fraction than the press-hardenable steel of the workpiece or workpieces.
- a further advantageous embodiment of the method according to the invention provides that the additional wire is supplied to the molten bath in a heated state.
- the filler wire is heated to a temperature of at least 50 ° C at least in a length section before being fed into the molten bath.
- inert gas inert gas
- Uncoated steel blanks or steel strips can also be welded together by the method according to the invention.
- the coating on aluminum or aluminum-silicon base in the edge region along the abutting edges to be welded together can be removed before the laser welding. This can be done by means of at least one energy beam, preferably a laser beam.
- Decoating is also possible. In this way, a deterioration of the weld by otherwise inadvertently introduced coating material can be reliably prevented, which during hot forming (press hardening) to
- Breakdowns in the hardness process can or would.
